Welcome to leyanda.de!

My name is Andreas Fiessler, electrical engineer and passionate hobbyist in my spare time. Beside my regular job as a research engineer my interests include all kinds of electronics, microcontroller, robotics, light effects, amateur radio (DH7AF) and much more.

This website is an attempt to collect and publish my previous and upcoming work on various DIY projects - or at least some of them.

If possible, I try to provide more or less detailed instructions, source code, and schematics so you can use it as a basis for your own work.
